Abstract (en)
[origin: EP3471202A1] A dielectric lens is provided. The dielectric lens is a cylindrical lens or an ellipsoidal lens whose cross-sectional profile is a quasi-ellipse, and the dielectric lens is formed by piling a plurality of units. Dielectric constant distribution of the units in the dielectric lens enables a non-plane wave in a minor axis direction of the quasi-ellipse to be converted into a plane wave through the dielectric lens. The units of the dielectric lens are prepared through extrusion, injection, molding, CNC machining, or a 3D printing process technology, and the units may be assembled through gluing, welding, structural clamping, or a connection directly printed through 3D printing. When the dielectric lens is applied to a muti-beam antenna, a system capacity of a communications system can be increased. In addition, compared with a conventional cylindrical Luneberg lens antenna, a thickness of the lens is reduced by using the muti-beam antenna.
